Is this your expected configuration? server server server | | | +----------+----------+ <-- cool gigabit ethernet backbone | GFS | iSCSI target doing RAID internally | disks You can also do the following to avoid GFS, if your NAS has iSCSI target has NFS capabilities: server server server | | | +----------+----------+ <-- cool gigabit ethernet backbone | NFS Appliance/Server | disks Or, if the data doesn't change often: server server server ^ ^ ^ +-<-<-<-<--+-->->->->-+ <-- cool gigabit ethernet backbone ^ ^ <-- one-way, periodic 'push' server of static content. Web servers | can not write to the main server disks On the front-end, you can use piranha + LVS to balance traffic between the web servers. Do *not* do the following, as the servers' caches/RAID metadata will not necessarily be in sync with each other: server server server | | | md RAID md RAID md RAID | | | +----+-----+-----+----+ | | iSCSI disk iSCSI disk -- Lon -- Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
